looking for advice from the pro`s

[boab type ra]

well sinse av broke the box av been looking at options for tunning it for next year but i am very limited due to lack of funds. can`t aford a 6 speed or uprated gears so am goin for a later ty754 so the info i need is:

will a bug eye wrx fit and what power can it handle?

what power can my engine handle its a wrx type ra with the original closed deck engine?

the mods r so far jap speed headers, 3" down pipe with fast flow cat reduced to 2.5" system, hypersingle clutch, apexi indution kit can i put more power in it safely.

another problem is i can`t go full boost sinse fitting the headers cause the fuel cut kicks in could`t keep up with a skoda vrs but bfore i could keep up with my bro`s wr1 so will a fuel cut deffender b ok to run or will i need to go for an apexi ecu.

just looking for advice so i can start striping it and get it ready for nxt summer so far this year av had 6 days use of it so am hoping to have more luck nxt year.

any advise welcome caus av not got a clue what to do.

get an aftermarket ECU and get it mapped properly. im selling a 4 plug V1 and V2? 92-96

As for gearbox a 754 will probably handle high 300's depending on the driver

Standard block is good for mid 300's but that would depend on history and how it has been treated.

A TY754VN4AA for example should hold up ok at 300/300 it did for me with 400/400 on a 2.5 with a 20G, with standard RA engine, you would need a matching 3.54 rear diff which are cheap as all uk newage WRX's use this diff.

I would advise changing to a mapable ecu cheapest options would be a Power FC or a SimTek.

I am assuming you are still on the standard 16G which will give you just under 300/300 if mapped properly by the likes of Andy F. You may need to upgrade the injectors if you have standard fit items.

thanks guys uve been very helpfull.

arch its still the 16g turbo but av got sti 440 injectors not fitted yet just need to save up for box and diff mite change the clutch to try save the box any advice on a clutch?

ciaranrb5 the engine is fine i hope done 70000 mile got the car 7 years ago with 45000km on the clock and av serviced it every year, always heated up before driving usually wash it when its ticking over and cooled down with the turbo timer. i will get in touch about the ecu av not got any spare cash at the moment thanks for the offer.

You would be better with 550's but to be honest in my opinion you should be looking at a mappable ECU as a matter of priority.

I am assuming you are using the standard ECU, but have changed the downpipe, induction system etc etc but still using the standard ECU and map not the best idea.

You should be able to pick up a TY754VN4AA box out of a blobeye WRX for around £300, poss another £100 for the diff at worst if you cant get it thrown in with the box.

Clutch, might be worth looking at the ACT range from the states, they are getting good revues and work out fairly cheap. Other than that that its an uprated exceedy.

thanks arch was planing getting it mapped when fitting the headers and also a front mount intercooler but ran out of funds just wanting a bit more power to annoy my brother

av put 550 injectors on my wish list

Boab, what boost you hitting? I've got a HKS fuel cut defender that you can either buy or borrow if you want. I've ran it for a few years with no probs but you need to be sure your getting enough fuel at the top end and are not hitting mad boost levels.

Also, rather than going to the expense of 550's why not get mark (lateral performance) to modify your 440's?

Cheers, Johnny.

hi johnny only hitting 14psi boost. thanks for the offer but think am goin to go down the road of an ecu and remap due to my mods goin for walbro fuel pump, 550 injectors, fuel pressure regulator and front mount intercooler hoping to get it over 300 bhp just need a bit more to keep infront of ma bro.

will look into getting 440 modified thanks m8

[johnnyr6]

A remap is defo the way to go. Why not speak to Andy F? An esl remap would work for what your after m8. Persoanlly if i was sticking with the maf thats what i'd look into.
